Hi Predrag,
It is hard to know when EXACTLY this problem surfaced - I just happened to notice the issue with this transaction.

I did find a successful coupon transaction that occurred on 5/20 for site#494. It was a different coupon code. You can see the difference in the logs after the line with the acceptance of valid coupon code.

I have updated plugins as my normal process during the past week. What type of plugin would impact this transaction? Note: I also ran into problems with this plugin on 5/14 regarding partial refunds - where even though it says "Partial" PayPal sent full refunds. There is another support ticket for this issue outstanding. I am losing some confidence with this plugin.

So this happened only on that specific code and with newly created ones you are not having any issues?

Did any of the caching or security plugins got updates as they can cause something like this?

You can check my answer regarding this on your other thread.
We are aware that there are some tweaks need for Pro Sites and that's why we are working on quite a big update that's supposed to come out soon.

Can you please let us know if the coupon issue is happening after the update is released?

Did you try disabling Wordfence just so we can check if something from that plugin is affecting coupons?

We don't give any ETA's because there is always possibility that there is a delay for some reason, but I can tell you that developers are working hard on it and we expect to release new version to members really soon.
